Although the estimated cumulative incidence of ovarian cancer by the age of 70 is 40% (95% CI 35–46%) for BRCA1 and 18% (95% CI 13–23%) for BRCA2 mutation carriers [6], the precise risk estimates vary according to the population under study, ascertainment method and applied statistical technique [7]. This evidence concerns the gene BRCA1 and ovarian carcinoma.
